Default AOA in the RV-12

I know that the Dynon is capable of displaying the "Angle of Attack" indicator. Why in the world would you not use it? Oh well. That's just one more reason that I want to build mine as an EAB.

Anyone else want AOA?

how are you going to get an AOA on there, and still have removable wings?

Default AOA and wing removal

I don't think that hooking up a couple of pitot lines would complicate the wing removal very much, or for that matter, a few extra wires. The O2 industry has some pretty nice quick connectors that should solve small tubing connection issues nicely. Also, in my case, daily removal of the wings is not a consideration.

Good luck with that.

I can tell you that those connectors do cause a little scoring on the tubing. repeated use on and off over lots of cycles will cause definate leaks.

why could you not have the AOA sensor through the prop shaft and spinner I am sure there is enough room for two tubes, does it have to be on the wing??

Odds are the AOA of the wing is not the same as the AOA of the spinner.

Cool AOA - RV-12

I agree, the AOA would be useful and not a lot of added trouble to hook up. The connectors (of which ever type) could be replaced as they wear out - not a factor in my mind. How about it, Van's?

The AOA is relative and taken care of in the set up.

I believe one of the Trutrak autopilots (i.e with the artificial horizon indicator) has a slow warning alarm feature that would act like AOA.

Default FlightDEK D180 AOA

It looks like the Dynon FlightDEK D180 is going to be installed in the RV-12. The D180 has the capability to display Angle of Attack using a single combination Pitot - AOA probe that is 3/4 inch in diameter according to the drawing on Dynon's website. http://www.dynonavionics.com/docs/D180_Feature_AOA.html Does anyone know if Van's will be supplying that probe? If not, is it feasible to install it in place of the pitot tube in the spinner? (Assuming EAB or previously certificated E-LSA).
